TIM E-STAM P.

SPECIFICATION forming part of Letters Patent No. 421,623, dated February 18, 1890.

Application filed July 13,1889. Serial No. 317,380. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES Il. SHAW, a citizen of the United States, residing at Brook;- lyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Time-Stamps, of which the following is a specification.

The invention consists in the combination and novel arrangement of parts, as hereinafter specified; and the object is to provide a stamp'whereby the time of day may be recorded in connection with other record, and, further, to provide a simple automatic inking device for the printing characters.

In the drawings, Figure 1 is a front view of the device with certain parts removed. Fig. 2 is a vertical section through the center of Fig. 1. Fig. 3 is a partial front View showing the clock-dial in place.` Fig/i is the representation of an imprint made from the stamp. Fig. 5 is a side elevation of the stamp in its normal position with one support broken away, and Fig. 6 shows the mechanism in position for printing or recording.

Similar letters of reference indicate like parts in all the figures.

Referring by letter to the drawings, A indicates the bed plate, here shown as arranged in a depression or recess a in the hollow base A. I prefer this bed A to have a slight rocking motion, and therefore provide it with a hemispherical projection a', which extends into a recess of corresponding shape in the base, and a screw a2 passes loosely through an opening in the base into the projection d.

B indicates the stamping-head having piv etal connection with the supports B', upstanding from the base A in the rear of the bedplate A. A

The stamping-head B comprises a boxing b, extending downward from acasing b,with

in which time mechanism (not shown) is arranged. Within the boxing b is a roller b2 and a smaller roller b3, over which endless bands b4 are adjustable. The bands b4 are provided with printing characters to kfindicate the month, the date of the month, and the year. A frame C is provided at one end with fixed type e and at its other end with a rotary or adjustable printing-stamp c', having a handle portion c2 extended through the frame, and by means of which the proper character or characters on the stamp c maybe adjusted into position for stamping. This frame O is removably secured to the lower end of the boxing by means of its hooked surfaces c3, extending over the back of the boxing, and the thumb-screw c4, extending through a tapped hole in the frame and impinging against the front of the boxing.

D is an endless belt, provided on its outer surface with printing characters indicating the hours and fractions thereof and the meridianmarks, as indicated in Fig. 4. This belt 'D is constantly rotated by time mechanism;

and with this end in view it is extended over a sprocket-wheel d, which is connected to the hour-hand post d of time mechanism (not shown) and is driven thereby. The lower portion of the endless belt extends around rollers d2 journaled in the lower portion of the boxing and the belt is provided with holes cl3, through which the sprockets d4 on the wheel d extend and prevent the belt from slipping, and therefore render the rotation of the belt positive with relation to the movelnent of the clock mechanism.

It will be observed that the rollers d2 are some distance apart, so that there is anex tended flat surface of the belt between the rollers, from which an impression is made to indicate the time of day in connection with a iixed pointer, as plainly shown in Fig. 4.'

To move the stamping-head forwardly and downwardly, l pivotally connect it to a lever E, which is here shown as bifurcated orprovided with the two arms e, which are fulcrumed at e to the supports B. Below the fulcrumpoints e the arms c are curved and have portions @2 turned outwardly at nearly right angles to the main portions, and between these portions e2 a yieldinglever E is fulcrumed by means of pins c3 extending from the lever into openings in the arms. v

An inking-roller F is j ournaled within the lever E', near its front end, as shown, and to provide a yielding pressure of this inkingroller over the type a spring f is secured at one end to the lever E', and has its opposite end projected into a cross-bar f between the portions c2.

It is evident that as the stamping-head is moved forwardly and downwardly by means of the bifurcated lever the inking-roller will be carried rearwardly over the printing characters, which are all in one planeandbeyond the same, as shown in Fig. G.

It is necessary that the stamping-head be held in a vertical position at all times, and for this purpose I provide the angle-links G, which are fulcrumed to the supports at g and have one end pivoted at g to the boxing and the opposite end pivoted at g2 to thelinks G', which I have shown as pivoted at one end to the lever E and having pivoted connections g3, which extend through slots in the base and engage with springs II, which serve to automatically return the stamping-head to its normal position after the stamping operation.

The springs Il are here shown as iiat springs, rigidly secured at one end within the hollow base; but it is evident that other forms of returning devices may be used without departing from the spirit of my invention.

Stops 71 on the supports coact with the lever E and arrest the rearward movement of the stamping-head.

\Vhat1 claim as my invention, and desire to secure by Letters Patent, is-

l. In a time-stamp, the combination, with time mechanism moving an endless type-belt, of a bed, a stamping-head, a support located in rear of the bed, and a connection between the stamping-head and the support, whereby the stamping-head may be moved forwardly and downwardly to reach the bed, substantially as specified.
